CE Compliance & Noise Considerations 7 Overview ……7-1 CE Standards and Directives …… 7-1 Safety Conditions ……7-2 Emissions/Immunity Conditions ……7-2 CE Enhancements for DBKs .…… 7-3 CE Compliance for System Expansion …… 7-3 Noise Considerations …… 7-4 Overview CE-compliant products bear the “CE” mark and include a Declaration of Conformity stating the particular specifications and conditions that apply.
For clarification, terms used in some Declarations of Conformity include: • pollution degree: any addition of foreign matter, solid, liquid or gaseous (ionized gases) that may produce a reduction of dielectric strength or surface resistivity.
CE Enhancements for DBKs The following CE enhancements are detailed in the DBK Cards and Modules User’s Manual (p/n 457-0905). • • • DBK41/CE Edge Guard (for DBK5, DBK8, and DBK44) Applicable cables and connectors CE Compliance for System Expansion The Daq devices are CE compliant at the time they leave the factory, and will remain in compliance providing that the conditions stated on their respective Declaration of Conformity cards continue to be met.
Noise Considerations Controlling electrical noise is imperative because it can present problems even with the best measurement equipment. Most laboratory and industrial environments suffer from multiple sources of electrical noise. For example, AC power lines, heavy equipment (particularly if turned on and off frequently), local radio stations, and electronic equipment can create noise in a multitude of frequency ranges.
Taking Measurements 8 Introduction …… 8-1 Scanning …… 8-1 Triggering …… 8-2 Synchronous I/O Operations…… 8-3 Asynchronous I/O Operations …… 8-5 Synchronizing Multiple Units …… 8-6 Using DBK Cards and Modules for Signal Conditioning ….. 8-8 Introduction With signal lines connected and a system up and running you can begin acquiring data. Specific connector details and pinouts are provided in chapter 4.
Triggering Triggering can be the most critical aspect of acquiring data. DaqScan/2000 Series devices support a full complement of trigger modes to accommodate a wide variety of applications. Hardware Analog Triggering. Many data acquisition products claim analog triggering, but rely on the PC to take readings and make a decision, which leads to uncertain and potentially long latencies.
Pre- and Post-Triggering Modes. Six modes of pre- and post-triggering are supported, providing a wide variety of options to accommodate any measurement requirement. When using pre-trigger, the user must use software-based triggering to initiate an acquisition. • No pre-trigger, post-trigger stop event. This, the simplest of modes, acquires data upon receipt of the trigger, and stops acquiring upon receipt of the stoptrigger event. • Fixed pre-trigger with post-trigger stop event.
Channel Sampling Interval In regard to analog input, DaqScan/2001 and DaqScan/2005 allow for programmable sampling intervals of 5 us, 10 us, or 1000 us on a per channel basis. This mode allows some DBK expansion channels [that change slowly for a higher degree of accuracy] to be sampled at a longer interval, and channels that change more rapidly to be sampled at a shorter interval. Each 5 µs, 10 µs, or 1000 µs interval reduces the maximum aggregate acquisition rate for the entire scan by that amount.
Synchronous Output Data Source (DaqScan/2001 and DaqScan/2004 only) DaqScan/2001 and DaqScan/2004 allow the data source for synchronized DAC output operations to be that of an internal memory-based buffer. The output data, for all channels, is contained in the buffer. Asynchronous I/O Operations Each DaqScan/2000 Series device allows asynchronous input of any counter or digital channel that is not currently configured for synchronous acquisition.
Synchronizing Multiple Units Up to four DaqScan/2000 Series devices can be synchronized to each other via their rear panel SYNC connectors and associated cables. Each device has two identical SYNC ports; either [or both] can be used to connect units. The DaqScan units can be scan-synchronized and triggered from any other SYNC-connected unit. Note that cables CA-74-1 and CA-74-5 are 1-foot and 5-foot in length, respectively. The total combined cable length of the Sync cables is not to exceed 15 feet (4.
In regard to synchronization, the following applies: • One of three signals can be used to drive the DaqScan/2000 Series acquisition scan rate. These are: − the internal acquisition pacer clock − an external acquisition pacer clock (for DaqScan/2001 and /2005 only) − the global sync (G-SYNC) input from the SYNC ports • Both the SYNC connector input and the external clock input can be divided down.
Using DBK Cards and Modules for Signal Conditioning The DBK signal-conditioning cards and module are designed for use with DaqLabs, DaqScans, DaqBooks, LogBooks, and various types of data acquisition boards, i.e., ISA, PCI, and compact-PCI types. The DBKs perform best when used with an acquisition device that can dynamically select channel, gain, and range. DBK cards and modules with dynamic channel and gain/range selection allow for high channel-to-channel scan rates with a variety of transducers.
Calibration 9 Overview …… 9-1 Using DaqCal.exe …… 9-1 Overview Daqscan/2000 Series devices are digitally calibrated at the factory. The digital method involves storing a correction factor on the circuit board for each range at the time of calibration. Whenever a particular range is selected, the appropriate calibration constant is automatically applied to a compensating DAC, thereby calibrating the specific range.
